AIR HEATER AND MOISTENER FOR CARBURETORS.

Application filed March 6, 1926. Serial No. 92,898.

This invention relates to a device for heating and moistening airdelivered to carbu- .retors.

forms of air stoves for heating either the air,

fuel or the vapors either before the fuel and air reaches thecarburetor, in the carburetor or by heating the intake manifold. Theresult is that the charge is not; only greatly overheated but the airhas been expanded too much so that the fuel is not effective to producethe proper .results during all operating conditions of the engine sincethe engine becomes overheated during heavy duty and much of the heatwhich should ordinarily have been dissipated from the engine is employedthrough the charge to increase the overheating. 7

. An object of the present invention is the provision of. a device forassociating with the radiator of an automobile for not only heating theair employed in the carburetor to a predetermined degree but formoistening theair in order in the first place to prevent theusual.refrigeration at the intake and for supplying suliicient moistureto aid in maintainingthe proper temperature of the firing chamber of theengine cylinders and thereby prevent preignition and decrease the carbondeposit in the cylinders of the,

7 motor. 7 Y

A further object of the invention is the provision of a device adaptedto be employed in a radiator ofan automobile and connected with the airconduit to-the'carburetor for supplying warm air to the carburetor andfor aiding in cooling the water in the radiator, the device including anair chamber provided with a pad Or other form of moisten er which isconstantly saturated .by reason of its connection with the overflow pipeof the radiator so that as the air passes thru the moistened pad andthrough the hottest portion of the radiator it will be warmed and besupplied consequently with a predetermined quantity of moisture to themixing chamber of the carburetor.

It has been attempted to A still further object of the invention is y Ithe provision of adevice adapted tobe placed in the radiator of anautomobile and connected with the air conduit of the carburetor forsupplying warm moistair to said carburetor and includes a conicallyshaped chamber mounted in the upper. header of the radiator with] thelower end. of the chamber being conneetedto the overflow pipeoftheradiator the upper end of the chamber being connected to a pluralityof tubes with a closed chamber also, located in theupper header and apipe connecting the closed chamber withthe carburetor.

This invention will be best Eunderstood from a. consideration of thefollowing d e- J tailed description, in view'of thteaccompanyingdrawings forming a part of the specifie cation; nevertheless it IS tobe'undei'stood that the invention is notconfined to the disclosure,being susceptible of such: changes 4 and :modifications which shalldefine no material departure from the salient features] of the inventionas expressed in theappended claims.

In the drawings: Figure l is a transverse; vertical section takenthrough the rear end of the radiator. Figure2 is a vertical sectiontaken through the air chamber. Figure 3 is a vertical section takenthrough the air 'moistener connected to the radiator.

Referring more particularly to the draw-.

ings, 10 designates a radiator having an upper header .11. into whichthe radiator tubes 12 extend. A cup-shaped container 13 is securedinspaced relation to the-under face of the bottom 11 of the upper header11 by straps 14 and is .reduced at its lower end and connected withanoverflow pipe 15 which extends downwardly and terminates adjacentthebottom of the radiator. The

spacing of the member 13=from the bottom 11 provides an air space 16'orpassage for the air at therrear ofthe radiator to the cup-shaped member13. 7' l A sponge or pad 18 of any suitable to be moistened by the waterwhich over-' flows from the header 11'. The. excess water fromapredetermined level in the U ma I terial is located in the cup 13 and isadapted header 11 passes through .a pipe 17 to cup 13 and then to thep1pe15 to the atmosphere below the radiator.
